BOTTLE-CAP.

SPECIFICATION forming part of Letters Patent No. 730,561, dated June 9, 1Q03.` Application Vtiled March 9, 1903. Serial No. 146,864. (No model.)

T0 all when@ t ptcty'corzccru:

Be it known that I, EDWIN NORTON, a citizen of the United States'. residing in New York, i'n the county of New York and State of New York, have invented a new and 'useful Improvelnentin Bott1e-Caps,of which the following is a specification. Y

My invention relates to improvements in bottle caps or closures for bottles, jars, or other vessels of glass or other material.

The object of myinvention is t0 provide a key-opening bottle cap or closure of a simple and efficient construction which may be cheaply manufactured, readily and conveniently applied to the bottle, jar, or other vessel, which will securely seal the bottle, jar, or vessel, and which at the same time may be easily opened by means of an ordinary key, such as is commonly used for key-opening cans.

My invention consists in the means I employ to practically accomplish this object or resultthat is to say, it consists, in connection with a bottle, jar, or other vessel having slit and tongue, and a tearing-strip extending from the tongue across the disk and formed by parallel scores or weakened lines, the scores or weakened lines being preferably eX- tended to the edge of the crimping-nan ge at the rim thereof opposite the tongue.

My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown or described. Y Y

In the accompanying drawings, forming a part of this specification, Figure 1 is a front elevation of a bottle cap or closure embodying.

my invention. Fig. 2 is a top or plan View. Fig. 3 is a vertical section on line 3 3 of Fig. l. Fig. 4t is a rear elevation. Fig. 5 is a detail section of the clamping-disk at right angles to the tearing-strip., Fig. 6 is a detail plan of the cork or sealing-disk, and Fig. 7 is a detail sectional View of the cork-holder disk.

In the drawings, A represents the bottle, jar, or other vessel having at the mouth of its neck a cap-holder groove or shoulder a.

C is the cork or sealing-disk, the same being made of any suitable impervious and compressible sealing material-such, for example, as a thin disk of cork or other suitable natural or artificial sealing material commonly used for this purpose.

B is the sheet-metal cork-holder disk, the saine having, preferably, a narrow depending retaining-ange b for keeping or holding the cork or sealing-disk C in place therein.

D is the sheet-metal clamp-disk, the same having a depending crimping-dange d extending around its whole circumference and adapted to be smoothly bent or crimped into or underv the cap-holder groove c' on the mouth of the bottle or jar. The clamp-disk D is provided at its dat or disk portion d with a tongue-slit d2, forming an upwardly-projecting tongue d3 of a tearing-strip d4, marked oi by scores or weakened lines d5, which extend from the tongue d3 across the clamp-disk D and preferably to the edge of its crimpingiiange d. The front end d6 of the tenguie-d3 does not extend quite tothe rim of the clampdisk D, thus leaving a marginal portion d7 intact or continuous to support the corkholder disk and sealing-disk at the rim, and thus securely clamping the sealing disk against the rim a of the bottle-neck or jar. F represents the key used in opening the bottle or jar, the same being of the ordinary construction commonly used for key-opening cans.

To open the bottle or jar provided with my bottle cap or closure, the tongue d3 of the tearing-strip is inserted in the slot f of the key, and then by turning the key the tearingsti'ip is Wound upon the key, thus dividing the clamp-disk into two part-s.

I claimp A 1. The combination with a bottle, jar or other vessel having an external shoulder at its mouth, of a cork or sealing-disk, a corkholder disk, and a clamp-disk having a depending crimping-ilange, and provided at its Vflat or disk portion Wit-h a tongue-slit and tongue, of a tearing-stri p extending from the tongue across the clamping-disk and marked oi by scores or weakened lines, substantially as specified.

2. In a closure for bottles, jars or other vessels, the combination with a cork or sealing-disk, of a clamp-disk having a depending crimping-ange and provided with a tongueslit and tongue at its fiat or disk portion, and with scores or weakened lines extending from the tongue across the clamping-disk, substantially as specified.

3. In a closure for bottles, jars or other vessels, the combination with a cork or sealingdisk, of a clamp-disk having a depending crimping-ange and provided With a tongueslit and tongue at its flat or disk portion, and
